Rossi, whose three-day family "vacation" was to Boston, did not take want to go down without a fight. On April 26, he responded to the school by posting a response on his Facebook page (and Twitter), which A Plus has screenshot.

Unexcused absences include such reasons as missing the bus, family vacations, or failure to provide a written excuse note upon the student's return to school. After three days of unexcused absence a warning notice will be sent to the parents or guardian. With the next unexcused absence, a criminal complaint will be filed without warning with the District Justice for court action.

Still, Rossi doesn't agree with the policy in the first place.

"My beef isn't really with the principal. We like her very much," he wrote. "It's the policy that stinks."

As stated in his response letter, he believes that his children's experiences outside of the classroom were invaluable.

Rossi, whose kids saw Boston Bombing survivors run in this year's race, learned about the city's history and of true perseverance, wrote: "These are things they won't ever truly learn in the classroom.

The note has gotten over 4,000 Facebook shares.

On April 27, Rossi posted on his page he was called in to meet with the principal.

A Plus has reached out to both Rossi and the Abington School District for comment and will update the story when they respond.
